People:
Pablo Hoffman opened this bug: "[1764761] Decimal comparison with None
fails in Windows".
It's not a Decimal problem, see the differente behaviour of this basic
test in Linux and Windows:
Python 2.5.1 (r251:54863, May 2 2007, 16:56:35) [GCC 4.1.2 (Ubuntu
4.1.2-0ubuntu4)] on linux2
>>> class C(object):
... def __cmp__(self, other):
... return NotImplemented
...
>>> c = C()
>>> print c < None
False
>>> print NotImplemented < None
False
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit
(Intel)] on win32
>>> class C(object):
def __cmp__(self, other):
return NotImplemented
>>> c = C()
>>> print c < None
True
>>> print NotImplemented < None
False
Here's where I stop: don't know where to keep looking... Does somebody
know why is a difference here?
Furthermore, we can check that is a problem regarding __cmp__:
>>> class C(object):
def __cmp__(self, other):
return NotImplemented
def m(self):
return NotImplemented
>>> c = C()
>>> print c < None
True
>>> print c.m() < None
False
This is not the first time I find an issue through Decimal regarding
NotImplemented, there was this thread:
http://mail.python.org/pipermail/python-dev/2005-December/059046.html
, but I don't know if that's a separate issue or not.
Thanks for your help!
